Viewing a reaction path diagram in a web browser.
|
|
|
|
This script uses the public webdot server at webdot.graphviz.org to
|
|
perform the rendering of the graph. You don't need to get the 'dot'
|
|
program to use this script, but you do need to be able to put your
|
|
output file where it can be served by your web server. You can either
|
|
run a local server, or mount the remote directory where your web files
|
|
are located. You could also modify this script to write the file
|
|
locally, and then upload it to your web server.
